Sleep talking, or somniloquy, is a common phenomenon where people speak during sleep, often without any memory of it afterward. Shouting in your sleep could be a symptom of sleep terrors, also known as night terrors, which are characterised by screaming, flailing, and intense fear during sleep. Sleep terrors are usually brief, lasting around 30 seconds, but can last up to a few minutes. They are more common in children, with 30% experiencing them, but they can also occur in adults and may be indicative of a more serious medical or mental health condition. Other potential causes of shouting in your sleep include REM sleep behaviour disorder (RBD) and parasomnias, which are disruptive sleep disorders that can cause abnormal behaviours during sleep.

What You'll Learn
Sleep terrors
During a sleep terror episode, an individual may exhibit signs of fear and panic, including screaming, crying, or getting out of bed. Sleep terrors can be difficult to distinguish from nightmares, but they are characterised by partial wakefulness, with the individual's brain being partially asleep and partially awake. This state can cause disorientation and confusion, and individuals often do not remember the episode the next morning.
If you or someone you know is experiencing sleep terrors, it is recommended to consult a healthcare provider or sleep specialist for guidance and management. Keeping a sleep diary can also help identify sleep patterns and any underlying problems contributing to sleep disturbances.

REM sleep behaviour disorder (RBD)
Shouting out in your sleep could be a symptom of a parasomnia, a type of sleep disorder characterised by behaviours or events that disrupt sleep. Parasomnias can occur during the latter part of the night, as you're falling asleep, during sleep, or right before you wake up.
One such parasomnia is REM sleep behaviour disorder (RBD). RBD is caused by a failure of the mechanism that normally keeps people still during dreams. During normal REM sleep, certain cells keep your muscles still so you don't act out your dreams. However, with RBD, this mechanism fails, and people are able to act out their dreams, often violently. This can cause poor sleep quality and unintended injuries to oneself or one's partner. People with RBD may shout, yell, grunt, punch, kick, grab, swear, laugh, cry, or make other aggressive movements. They may recall dream content associated with the behaviour if they wake up, such as calling for help, trying to hit something, or trying to defend themselves.
RBD is more common among adults and people with neurodegenerative diseases like Parkinson's disease, Lewy body dementia, or multiple system atrophy. It may also be the first symptom of these conditions, appearing several decades before their onset. Other risk factors for RBD include the use of certain medications, such as antidepressants, and the use or withdrawal of alcohol or illicit drugs.
A detailed sleep history is sometimes enough to diagnose RBD, especially if there is already a diagnosis of an associated condition. A one- or two-night inpatient sleep study may also be used to diagnose RBD; this is known as polysomnography, which involves taking multiple measurements during sleep, including muscle tension during REM sleep. Management of RBD includes providing physical safeguards in the sleep environment and, in some cases, medication. Sleep hygiene, which refers to a healthy approach to sleep and wakefulness, can also help improve sleep quality and reduce symptoms.

Sleep paralysis
Shouting out in your sleep could be a symptom of a parasomnia, a type of sleep disorder characterised by disruptive behaviours or events that affect sleep. Parasomnias can occur as you're falling asleep, during sleep, or right before you wake up.
Sleep terrors, for example, are parasomnias that cause people to wake up suddenly in a state of fear. They usually last for 30 seconds but can last up to a few minutes. During sleep terrors, people may shout, scream, or cry out in fright. Sleep terrors are usually brief but can be quite distressing for the person experiencing them and those around them.

Sleepwalking
Shouting out in your sleep may be a symptom of a sleep disorder. Sleep talking, or somniloquy, can occur alongside sleepwalking, sleep terrors, and REM sleep behaviour disorder (RBD). Sleepwalking, or somnambulism, is a parasomnia characterised by getting out of bed and moving about with your eyes open while remaining asleep. Sleep terrors, or night terrors, are episodes of screaming, crying, thrashing, and kicking during sleep, often accompanied by a racing heart rate, dilated pupils, fast breathing, and sweating. RBD, on the other hand, involves vocalisations such as talking, shouting, grunting, laughing, or swearing, as well as physical acting out of dreams, which can include violent movements.
The causes of sleepwalking are not always clear, but it is believed to be linked to slow-wave sleep, the deepest stage of sleep that occurs in the early part of the night. Some researchers suggest that individuals prone to sleepwalking or night terrors may have difficulty maintaining this deep sleep stage, making them susceptible to quick arousals and increasing the likelihood of parasomnias. Additionally, sleepwalking may be influenced by neurological diseases, mental health conditions, genetics, or certain medications.
To reduce the risk of sleepwalking and associated sleep disorders, practising good sleep hygiene is essential. This includes maintaining a regular sleep schedule, minimising stimulants like caffeine, and creating a calm and quiet sleep environment without distractions like TV or music playing in the background. If sleepwalking persists or poses safety concerns, it is advisable to consult a healthcare professional for further guidance and potential treatment options.

Treatment options
Shouting in your sleep is a type of parasomnia—a sleep disorder characterized by abnormal behaviours that occur during sleep. It can be caused by nightmares, night terrors, sleep disorders like REM sleep behaviour disorder (RBD), stress, anxiety, or underlying medical conditions. Treatment options for shouting in your sleep depend on the underlying cause and severity of the condition. Here are some possible treatment options:
Managing Underlying Conditions
Treating any underlying medical or psychological conditions that may be contributing to sleep shouting, such as PTSD, anxiety disorders, or other sleep disorders. This may involve medication or therapy.
Improving Sleep Hygiene
Establishing regular sleep routines, ensuring a comfortable and safe sleep environment, and avoiding substances like alcohol or caffeine close to bedtime can help reduce the frequency of sleep shouting. Maintaining good sleep hygiene habits, such as getting seven to nine hours of sleep per night, turning off lights and electronic devices, and keeping the room temperature cool, can also be beneficial.
Medications
In some cases, medications may be prescribed to manage symptoms associated with sleep disorders or to address underlying conditions contributing to shouting episodes.
Behavioral Therapies
Cognitive-behavioral therapy (CBT) or techniques such as imagery rehearsal therapy can be used to reduce nightmares or night terrors that trigger shouting in sleep.
Sleep Study and Diagnosis
A sleep study or polysomnogram can help healthcare providers monitor and record your brain waves, heart rate, eye movements, and breathing during sleep. Video electroencephalogram (EEG) or sleep EEG tests can also help visualize brain activity during sleep. These tests can aid in diagnosing the specific type of parasomnia and ruling out other conditions with similar symptoms.
It is important to consult with a healthcare professional to determine the most appropriate treatment plan for shouting in your sleep, as it may vary depending on the underlying cause and severity of the condition.
